BACKGROUND Technical Field

The present invention relates to compounds for organic electric elements, organic electric elements comprising the same, and electronic devices thereof.

Background Art

In general, an organic light emitting phenomenon refers to a phenomenon in which electric energy is converted into light energy of an organic material. An organic electric element utilizing the organic light emitting phenomenon usually has a structure including an anode, a cathode, and an organic material layer interposed therebetween. In many cases, the organic material layer has a multi-layered structure each composed of different materials in order to improve efficiency and stability of an organic electric element, and for example, may include a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer, an electron injection layer, or the like.

A material used in an organic material layer of an organic electric element may be classified into a light emitting material and a charge transport material, such as a hole injection material, a hole transport material, an electron transport material, an electron injection material and the like depending on its function. Further, the light emitting material may be divided into a high molecular weight type and a low molecular weight type according to its molecular weight, and may also be divided into a fluorescent material derived from electronic excited singlet states and a phosphorescent material derived from electronic excited triplet states according to its light emitting mechanism. Further, the light emitting material may be divided into blue, green, and red light emitting materials, and yellow and orange light emitting materials required for better natural color reproduction according to its light emitting color.

Meanwhile, when only one material is used as a light emitting material, there occur problems of shift of a maximum luminescence wavelength to a longer wavelength due to intermolecular interactions and lowering of the efficiency of a corresponding element due to the deterioration in color purity or a reduction in luminous efficiency. On account of this, a host/dopant system may be used as the light emitting material in order to enhance the color purity and increase the luminous efficiency through energy transfer. This is based on the principle that if a small amount of dopant having a smaller energy band gap than a host forming a light emitting layer is mixed in the light emitting layer, then excitons generated in the light emitting layer are transported to the dopant, thus emitting light with high efficiency. With regard to this, since the wavelength of the host is shifted to the wavelength band of the dopant, light having a desired wavelength can be obtained according the type of the dopant.

Currently, the power consumption is required more and more as size of display becomes larger and larger in the portable display market. Therefore, the power consumption is a very important factor in the portable display with a limited power source of the battery, and the situation is such that efficiency and life span issue also must be solved.

Efficiency, life span, driving voltage, and the like are correlated with each other. For example, if efficiency is increased, then driving voltage is relatively lowered, and the crystallization of an organic material due to Joule heating generated during operation is reduced as driving voltage is lowered, as a result of which life span shows a tendency to increase. However, efficiency cannot be maximized only by simply improving the organic material layer. This is because long life span and high efficiency can be simultaneously achieved when an optimal combination of energy levels and T1 values, inherent material properties (mobility, interfacial properties, etc.), and the like among the respective organic material layer is given.

Therefore it is required to develop a light emitting material that has high thermal stability and can achieve efficiently a charge balance in the light-emitting layer. That is, in order to allow an organic electric element to fully exhibit the above-mentioned excellent features, the material consisting an organic material layer of the element such as a hole injection material, a hole transport material, a light emitting material, an electron transport material, an electron injection material, or the like should be prerequisite to support by a stable and efficient material, and among them, it is necessary to develop host material for a light emitting layer.

The first electrode 110 may be an anode (positive electrode), and the second electrode 170 may be a cathode (negative electrode). In the case of an inverted organic electric element, the first electrode may be a cathode, and the second electrode may be an anode.

The organic material layer may comprised a hole injection layer 120, a hole transport layer 130, a light emitting layer 140, an electron transport layer 150, and an electron injection layer 160. Specifically, a hole injection layer 120, a hole transport layer 130, a light emitting layer 140, an electron transport layer 150, and an electron injection layer 160 are formed on the first electrode 110 in sequence.

Preferably, a layer for improving the luminous efficiency 180 may be formed one side of sides of the first electrode 110 and the second electrode 170, wherein one side is not facing the organic material layer, as a result the luminous efficiency of an organic electric element can be improved.

For example, the light efficiency improving layer 180 may be formed on the second electrode 170, as a result, in the case of a top emission organic light emitting diode, the optical energy loss due to surface plasmon polaritons (SPPs) at the second electrode 170 may be reduced and in the case of a bottom emission organic light emitting diode, the light efficiency improving layer 180 may serve as a buffer for the second electrode 170.

In addition, according to another embodiment of the present invention, the organic material layer may be a form formed by a plurality of stacks, wherein the stacks comprise a hole transport layer, a light emitting layer, and an electron transport layer, respectively. This will be described with reference to FIG. 3.

Referring to FIG. 3, two or more sets of stacks of the organic material layers ST1 and ST2 may be formed between the first electrode 110 and the second electrode 170 in the organic electric element 300 according to another embodiment of the present invention, wherein the organic material layers are consisted of multiple layers, respectively, and the charge generation layer CGL may be formed between the stacks of the organic material layer.

Specifically, the organic electric element according to the embodiment of the present invention may comprise the first electrode 110, the first stack ST1, the charge generation layer CGL, the second stack ST2, and the second electrode 170 and the light efficiency improving layer 180.

When a plurality of light emitting layers are formed in a multi-layer stack structure as shown in FIG. 3, it is possible to manufacture an organic electroluminescent element that emits not only white light but also various colors, wherein the white light is emitted by the mixing effect of light emitted from each light emitting layer.

The mixture of the compound represented by Formula 1 and the compound represented by Formula 2, or the compound represented by Formula 3 comprised in Formula 1 can be used as material of a hole injection layer 120, 320, 420, a hole transport layer 130, 330, 430, a buffer layer 210, an emission-auxiliary layer 220, an electron transport layer 150, 350, 450, an electron injection layer 160, a light emitting layer 140, 340, 440, or a layer for improving luminous efficiency 180, preferably as material of an emission-auxiliary layer 220, a light emitting layer 140, 340, 440 or a layer for improving luminous efficiency 180, more preferably, as host material of a light emitting layer 140, 340, 440.

Even if the core is the same core, the band gap, the electrical characteristics, the interface characteristics and the like may be different depending on which substituent is bonded at which position. Therefore, it is necessary to study the selection of the core and the combination of the core and the sub-substituent bonded to the core. In particular, long life span and high efficiency can be simultaneously achieved when the optimal combination of energy levels and T₁ values, inherent material properties (mobility, interfacial properties, etc.), and the like among the respective layers of an organic material layer is achieved.

Therefore, energy level and T₁ value between the respective layers of the organic material layer, inherent material properties (mobility, interfacial properties, etc.) and the like can be optimized by using the mixture of the compound represented by Formula 1 and the compound represented by Formula 2, or by using the compound represented by Formula 3 comprised in Formula 1 as material of a light emitting layer 140, 340, 440 and/or an emission-auxiliary layer 220, and thus it is possible to simultaneously improve the lifetime and efficiency of the organic electric element.

The organic electric element according to an embodiment of the present invention may be manufactured using various deposition methods. The organic electric element according to an embodiment of the present invention may be manufactured using a PVD (physical vapor deposition) method or CVD (chemical vapor deposition) method. For example, the organic electric element may be manufactured by depositing a metal, a conductive metal oxide, or a mixture thereof on the substrate to form the anode 110, forming the organic material layer comprising the hole injection layer 120, the hole transport layer 130, the light emitting layer 140, the electron transport layer 150, and the electron injection layer 160 thereon, and then depositing a material, which can be used as the cathode 170, thereon.

Also, the organic material layer may be manufactured in such a manner that the fewer layers are formed using various polymer materials by a soluble process or solvent process, for example, spin coating, nozzle printing, inkjet printing, slot coating, dip coating, roll-to-roll, doctor blading, screen printing, or thermal transfer, instead of deposition. Since the organic material layer according to the present invention may be formed in various ways, the scope of protection of the present invention is not limited by a method of forming the organic material layer.

The organic electric element according to an embodiment of the present invention may be of a top emission type, a bottom emission type, or a dual emission type depending on the material used.

In addition, the organic electric element according to an embodiment of the present invention may be selected from the group consisting of an organic light emitting diode, an organic solar cell, an organic photo conductor, an organic transistor, an element for monochromatic illumination and an element for quantum dot display.

Fabrication and Evaluation of Organic Electronic Element

[Example 1] to [Example 102] Red OLED (Mixed Phosphorescent Host of a Light Emitting Layer

After vacuum depositing 4,4′,4″-tris[2-naphthyl(phenyl)amino]triphenylamine (abbreviated as “2-TNATA”) film on an ITO layer (anode) to form a hole injection layer having a thickness of 60 nm, wherein the ITO layer was formed on a glass substrate, 4,4′-bis[N-(1-napthyl)-N-phenylamino]biphenyl (abbreviated as “NPD”) film was vacuum-deposited with a thickness of 55 nm on the hole injection layer to form a hole transport layer.

Next, a light emitting layer with a thickness of 30 nm was formed on the hole transport layer. As shown in Table 8, a mixture of a compound represented by Formula 1 of the present invention (host 1) and a compound represented by Formula 2 of the present invention (host 2) in a weight ratio of 3:7 was used as a host and bis-(1-phenylisoquinolyl)iridium(III) acetylacetonate (abbreviated as “(piq)₂lr (acac)”) was used as a dopant, where the host and dopant were used in a 95:5 weight ratio.

Next, a film of (1,1′-biphenyl-4-olato)bis(2-methyl-8-quinolinolato)aluminum (abbreviated as “BAlq”) was vacuum-deposited with a thickness of 10 nm on the light emitting layer to form a hole blocking layer.

Subsequently, after mixing tris-(8-hydroxyquinoline)aluminum (abbreviated as “Alq₃”) and bis(10-hydroxybenzo[h]quinolinato)beryllium (abbreviated as “BeBq₂”) in 1:1, the mixture was deposited on the hole blocking layer to form an electron transport layer having a thickness of 45 nm

Next, LiF on the electron transport layer was deposited to a thickness of 0.2 nm and then Al was deposited to a thickness of 150 nm to form a cathode. In this way, the OLED was completed.

From Table 8, it can be seen that the driving voltage, efficiency and lifetime of the element are remarkably improved when the mixture of the compound represented by Formula 1 and the compound represented by Formula 2 of the present invention is used as a phosphorescent host (Examples 1 to 90), compared with the case of using the compound represented by the formula 1 alone (Comparative Examples 1 to 4) or using a mixture of comparative compounds (Comparative Examples 5 to 6).

Comparing Comparative Examples 1 to 6, the characteristics of the element are further improved when the mixture of two kinds of comparative compounds is used (Comparative Examples 5 to 6) than when the compound of the present invention is used alone (Comparative Examples 1 to 4).

In addition, comparing Comparative Examples 5-6 and Examples of the present invention, the driving voltage is lower and the efficiency and lifetime are remarkably improved when the mixture of the compound represented by Formula 1 and the compound represented by Formula 2 of the present invention is used as a host, compared with the case of using the mixture of two kinds of comparative compounds.

From these results, the inventors of the present invention determined that a mixture of the mixture of the compound represented by Formula 1 and the compound represented by Formula 2 had new properties other than those of each compound, and thus, PL lifetime of each of the compounds and the mixture was measured, respectively. As a result, in the case of the mixture of the compound represented by Formula 1 and the compound represented by Formula 2 of the present invention, it was confirmed that a new PL wavelength was formed unlike the case of a single compound.

This is because when the mixture of the compounds of the present invention is used, not only electrons and holes are moved according to the energy levels of the respective materials, but also electrons and holes are moved or energy is transferred according to a novel region with a new energy level formed by mixing and thus the efficiency and lifetime is increased. This is an important example of showing the energy transfer and the emitting process by exciplex of the mixed thin film when the mixture of the compounds of the present invention are used.

In addition, when the polycyclic compound represented by the formula 1 with the high stability for holes as well as electrons and the compound represented by the formula 2 with the strong hole characteristics are mixed, the electrons blocking ability is improved and more holes move quickly and easily into the emitting layer due to the high T1 and LUMO energy values. As a result, as the charge balance increases in the light emitting layer, light is emitted well inside the light emitting layer, not at the hole transport layer interface, and this also reduces the degradation of the HTL interface, thereby the driving voltage, efficiency and lifetime of the element are maximized. That is, when the mixture of the compounds represented by Formulas 1 and 2 is used as a host, the performance of the entire device is greatly improved by electrochemical synergy.

Referring to Table 9 above, it can be seen when the first host and the second host are mixed at 3:7, the driving voltage, efficiency, and lifespan are excellent, and as the ratio of the first host increases, the characteristics of the element decrease. This is because the charge balance in the light emitting layer is maximized as the amount of the compound represented by the formula 2 having a stronger hole transport property than the compound represented by the formula 1 is increased.

[Example 107] to [Example 118] Red OLED

After vacuum depositing 2-TNATA film on an ITO layer (anode) to form a hole injection layer having a thickness of 60 nm, wherein the ITO layer was formed on a glass substrate, NPD film was vacuum-deposited with a thickness of 60 nm on the hole injection layer to form a hole transport layer.

Next, a light emitting layer with a thickness of 30 nm was formed on the hole transport layer. As shown in Table 10, the compound represented by Formula 3 of the present invention was used as a host and (piq)₂Ir (acac) was used as a dopant, and dopant was doped so that their weight ratio was 95:5.

As can be seen in Table 10, the organic electroluminescent element using the compound of the present invention as a phosphorescent host has improved the driving voltage, efficiency and lifetime compared to the case of using the comparative compound 4.

Comparative compound 4 and the compound of the present invention is different in the bonding position of the triazine substituent bonded to naphthobenzofuran.

When comprehensively judging the device data of Table 10, the driving voltage, efficiency and lifetime of the element are greatly improved when using a compound of the present invention as a host material rather than the comparative compound 4, wherein in the case of Comparative Compound 4, the triazine substituent is substituted at position 4 of naphthobenzofuran, and in the case of the present invention, it is substituted at position 1 of naphthobenzofuran. In particular, when the compound of the present invention comprising a substituent containing naphthyl in the triazine substituent moiety is used as a host material, the driving voltage and efficiency are greatly improved, and when the compound having a biphenyl as a substituent is used, the lifetime is greatly improved.

The above results can be seen to be due to the torsion angle. Table 11, as seen as FIG. 4, is a photograph taken from various aspects of the twist angle of 4-naphthobenzofuran such as Comparative Compound 4 and 1-naphthobenzofuran derivative such as Compound 2-109 of the present invention.

In Table 11 (FIG. 4), each drawing shows the image of a three-dimensional structure of Comparative Compound 4 and the compound 2-109 of the present invention in front, horizontal axis 60°, horizontal axis 90°, vertical axis 90° using the Chem3D program MM2 minimize energy method of Perkin Elmer, respectively.

Referring to Table 11 (FIG. 4), 4-naphthobenzofuran derivatives having a torsional angle of 0.9° with triazine, such as Comparative Compound 4, are nearly torsionless and have very high planarity. On the other hand, 1-naphthobenzofuran derivatives such as the present invention have a planarity that is significantly different from that of Comparative Compound 4 since 1-naphthobenzofuran derivatives are more twisted with triazine, wherein a torsion angle is 10.2°.

Therefore, the compound of the present invention which is a relatively steric structure can reduce the degree of electrical polarization by weakening the intermolecular van der Waals force and lower the crystallinity of the thin film by weakening the intermolecular interaction. Moreover, when used as a light emitting layer material, this steric property can cause a certain distance from the electrochemically unstable dopant, which can ultimately increase the stability of the light emitting layer.

These comprehensive characteristics appear to improve the lifetime and characteristics of the element when the material is deposited.
